Mood Ring: Put on an iRing, Wave Your Hands in front of iPhone, iPad for 3D Control [$25]

Put a ring on it: camera tracking allows 3D gestural control on any iOS device. Clearly targeted partly at non-musicians, IK hopes to give you a fun way to control an iPhone, iPad, or computer software beyond touch.

But this is definitely a new take. IK Multimedia have a plastic “iRing” you wear on your finger that gives you control of your iPhone, iPad, or iPod touch.

The system uses the internal, front-facing camera on your iOS device to track the position of your hand. The dots on the rings are a marker that the camera follows through space. There are actually markers on both sides, so you have control whether you’re facing your device palm-forward or with the back of your hand.

X and Y position, as well as Z position (distance from the phone or tablet) are all assignable. You can also use two rings at once, for six simultaneous controls.

Of course, this is all meaningless if you don’t have anything to control. iRing comes with two apps – iRing Music Maker and iRing FX and Control. The latter can be used in conjunction with other apps, too, either by routing audio to them (via AudioBus or Inter-App Audio), or as a MIDI controller for those apps. (Confirmed: you can send MIDI to either other apps or to the desktop.)

X, Y, and Z are all assignable, including via two free apps from IK. Photos courtesy IK Multimedia.

iRing Music Maker: Similar to their GrooveMaker app, says IK, this app lets you assemble music from grooves, loops, and the like. Here’s what’s crazy: you switch loops, change effects, all from the ring.

iRing MusicMaker is a groove-based app that uses the rings. What’s unique here is how ambitious that is – even swapping loops is controlled gesturally.

If all you want to do is control some effects parameters in desktop software like Ableton, that’s possible, too.

Because it uses the camera, I don’t expect this to have the accuracy and latency performance of a dedicated device. However, I am very keen to see how well it does work – and there’s a big advantage to being able to use the camera your device already has. And I’ll hold off on any real judgment on performance until I try this.

Also, we have a “wave-your-hands” featurette in store for you soon, given these various options.

Whew, we got through that whole story without a single Tolkien reference.
